-Applause "blue" roses are apparently not available for growth in gardens, but for sale by florists.

-They are purple, not blue.

I'm very curious if a truly blue rose will eventually come to exist though. And if such a thing would ever be available in gardens (or regulated strictly and kept in special locations. Or just never sold to the public because it could drive down the price that could be asked for the flowers.)

I'm aware that not everyone is fond of genetic engineering, and because this is not a political or overly scientific forum I won't ask you to be, but nonetheless it's still a very interesting application of the science.
